Compress or expand letter spacing
Fine tune the distance between the individual characters of words to create titling effects and to improve readability.
The amount of space between two adjacent letters of a word can be reduced by specifying a negative value, or increased by specifying a positive value.
Use any of these font-relative typographic units:
|rem||relative em||The |
|ch||"0"||The advance measure (the width) of the current font's "0" glyph|
|ic||ideograph count||The advance measure (the width) of the current font's "水" ideograph|
Or use any of these fixed size units which are independent of the current font:
|in||inch||A size equal 96px|
|px||pixels||A size equal to 1/96 inch|
|pt||point||A size equal 1in/72 = 1.33px|
|pc||pica||A size equal 1in/6 = 12pt = 16px|
|cm||centimeter||A size equal to 96px/2.54 = 37.8px|
|mm||millimeter||A size equal to 96px/25.4 = 3.8px|
|Q||quarter millimeter||A size equal to 96px/1016 = 0.94px|
